Automobile racing began soon after the first cars were built. Although some cars used for racing are so specialized that they are quite useless on the streets, most differ only slightly from standard makes and thus can be used for ordinary driving as well as racing. Racing cars are usually single seaters built solely for racing. Sports cars that seat two people are true dual purpose cars which can be raced or used for street driving.
The kinds of races are typically differentiated by the courses on which they are run. One kind is the oval track while another is a run on public roads closed off for the race or on a special track designed to simulate the conditions of actual road racing. Still another is a run on a straight course which is actually a race against the clock rather than against other cars.

The different types of gasoline car engines are identified by the number of cylinders and the manner in which these cylinders are laid out. The 3, 4, 5 and 6 cylinder engines have their cylinders arranged in a row while the V-6, V-8, V-10 and V-12 configurations have theirs arranged in two side by side banks of cylinders forming a V. Another variation uses two opposing banks of cylinders found in flat engines used in vehicles such as the Porsche and Subaru.
A gasoline car engine starts working when the ignition key is turned which closes a switch that provides electricity to the battery. Energy for the starter is given by the electricity which turns the geared flywheel attached to the crankshaft’s gear. This in turn makes the fuel pump draw gasoline from the gas tank to force it into the carburetor where it will mix with air. The vaporous mixture produced is received by the individual cylinders through the intake manifold and intake valves.

BMW prides itself as the maker of the ultimate driving machine but it is quite interesting to note that it started out as a manufacturer of aircraft engines. The 3-letter acronym stands for Bayerische Motoren Werke or Bavarian Motor Works. Motor forms the key part of every product built by BMW.
The personalities behind the original BMW included Karl Friedrich Rapp who earlier established Rapp-Motorenwerke and Gustav Otto of Gustav Flugmaschinefabrik. Otto was the son of the man who invented the four-stroke internal combustion engine. Bayerische Flugzeug-Werke or Bavarian Aircraft Works was formed when the two companies merged. It soon became the Bayerische Motoren Werke GmbH and was formally reorganized as such in March 7, 1916. Keep reading →

Primarily designed to carry people from one place to another, cars should be equipped with features that would ensure safety of its passengers. Car safety becomes an even more major concern when the vehicle is intended to serve the needs of a family. Although entertainment features ensure that kids stay pacified during the trip, it is the safety features that could guarantee that the family is protected enough to be able to enjoy the many joys of life such as entertainment.
Car safety basics include anti-lock brakes (ABS), side-curtain bags and electronic stability control (ESC). Through the rapid application of intermittent brake pressure, ABS is able to prevent a vehicle’s wheel from locking up. This feature provides an average driver more control during emergency situations. Generally offered for front occupants only due to potential injury risk to kids in child-safety seats, the side-curtain bags provide protection to the torso in side-impact crashes and also help keep passengers inside the vehicle in an event of a roll-over.
ESC gives the driver more control during maneuvers that are urgent in nature. It uses sensors for close monitoring of the vehicle’s actual path as related to the intended path using inputs on steering, brake and throttle.

One technology that is all too easily taken for granted is that of transmission. Under normal use, modern transmissions last long enough thereby causing no real worries for most new car shoppers.
What is important pertains to the matter of smooth shifting, good performance and fuel economy. Traditionally, manual transmissions provide better mileage than automatics but this is beginning to change with the new generation of electronically controlled automatics.
The transmission’s job is to strike the right balance between responsiveness and efficiency by matching a vehicle’s driving speed to the engine speed. Having more gears provide a better match and smoother shifts which explains why the number of speeds in transmissions has been increasing.
